Simon:

While I do serve as a nanny for several LEM Lists, the G-Books List is not
one of mine.  I wrote the reminder because the Original Poster of this
thread had already sent it to two wrong lists.

The List Owner sets the parameters and rules for all LEM Lists; we volunteer
nannies merely try to help him maintain some order and sense on the lists.
For all LEM Lists, he includes some simple words about list purpose in the
trailer of every message for all to read and follow.

As the owner of numerous Apple laptops, G4, G3, pre-G and stone-age (I have
a Macintosh Portable and a PowerBook 100), I subscribe to the G4 'Book,
G-Books and PowerBook Lists.  There are lots of good knowledgeable folks on
all three lists.  Why not send inquiries to the appropriate list, take
advantage of their expertise, and stop annoying other members with OT
messages?

See you on the G4'Books List.


Now back to this OT thread.  Even though I do not own this specific
PowerBook G4, I was sufficiently curious about the OP's problem that I took
a quick look through its Apple Service Manual.  The following
TroubleShooting section intrigues me, but I am not sure about its relevance.

"Caps lock LED power check"

There are situations when the system is giving indications that it is shut
down (no hard
drive access, screen is dark, no blower, and so on). However, the logic
board may still be running. In this case, the logic board is drawing power
and generating heat.

Warning: In this situation, if the computer is put in an enclosed
environment like a
carrying bag, the computer can overheat.

Check this situation by pressing the caps lock key. If the LED glows, the
PMU is running on the logic board. After pressing the caps lock key and
perhaps other methods of waking it up fails, hold the power button down for
six seconds to force a shut down of the computer.  Restart the system to
check if it boots up normally.
